CRIS v10: Update drivers/gpio.c, fix locking and general improvements.

- Change all spin_lock/local_irq_save to spin_lock_irqsave.
- Change multiple returns in functions where we have a lock to goto out.
- Correct number of arguments to gpio_poll_timer_interrupt, gpio_pa_interrupt.
- Break out gpio_write logic to smaller functions to make it readable.
- In setget_input and setget_output, avoid extra if-indent level.
- Change name LED_* -> CRIS_LED_* to avoid name clash.
- Don't use braces around single statement ifs.
- Fix whitespace errors.
- Remove useless CVS id and log.
